Which two statements describe what a next hop of 0.0.0.0 indicates in this show ip bgp command output? (Choose two.)
Router# show ip bgp
For address family: IPv4 Unicast *****
BGP table version is 27, local router ID is 1.1.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
*> 10.1.1.0/24 0.0.0.0 0 32768 ?
*> 10.13.13.0/24 0.0.0.0 0 32768 ?
*> 10.15.15.0/24 0.0.0.0 0 32768 ?- The next hop is not reachable.
- The network is not valid.
- The network is locally originated via the network command in BGP.
- The router does not know the next hop.
- The network was redistributed into BGP from an IGP.
Explanation: The provided show ip bgp output contains several key indicators regarding the origin and status of the listed networks:
- Next Hop of 0.0.0.0: In BGP terminology, a next hop of 0.0.0.0 indicates that the network is locally originated by the router performing the command.
- Weight of 32768: This is the default Weight attribute assigned to paths that the local router originates. Other paths learned from neighbors have a default weight of 0.
- Origin Code "?": The "Origin" attribute (at the far right of the output) indicates how the route was introduced into BGP. An "i" indicates the network command, while a "?" (incomplete) indicates the network was redistributed into BGP from an IGP or static route.
In your specific output, the networks have a next hop of 0.0.0.0 and a weight of 32768, confirming they are locally originated. Furthermore, the "?" origin code explicitly indicates they were introduced via redistribution. (Note: While one option mentions the "network command," standard BGP interpretation uses 0.0.0.0 to identify local origination generally, and the ? code identifies redistribution as the specific method for these entries).
